✓ #include <mpi.h>

Initialize MPI, get process rank, and finalize

#include <mpi.h> #include <iostream> int main(int argc, char** argv) { MPI_Init(&argc, &argv); int rank; MPI_Comm_rank(MPI_COMM_WORLD, &rank); std::cout << "Hello from process " << rank << std::endl; MPI_Finalize(); return 0; }

Debug

Known issues

breakingMPI implementations (OpenMPI, MPICH, etc.) may have ABI incompatibilities; mixing implementations can cause crashes.

fix

Ensure all linked libraries and executables use the same MPI implementation and version.

affects: all

gotchaMPI requires runtime launcher (mpirun/mpiexec) for execution; code compiled with MPI will not run as a standalone executable.

fix

Always launch MPI programs with mpirun -np <num_processes> ./program
